Notes:
Preparation of polycarbonates from a quinonediol and phosgene, and from the quinonediol and various bischloroformates, is described. Some of the bischloroformates were prepared from poly(ethylene oxides) with two terminal hydroxyl groups by phosgenation. The quinone groups incorporated into the polymer chain were reduced to hydroquinone groups. Some of these polymers were titrated oxidatively in 90% acetic acid. Their redox behavior cannot be described by a simple Nernst equation. It is assumed that the differences between theoretically expected and experimentally obtained potentials express the amount of work needed to reshape the polymer coil according to a thermodynamically stable distribution of the redox groups.
